    摘要: An adhesive composition for metal-clad laminates which comprises:(a) 100 parts by weight of a polyvinylbutyral having an average polymerization degree of from 500 to 3,000 and a degree of butyralization of at least 60 mol %,(b) from 10 to 200 parts by weight of an epoxidized polybutadiene per 100 parts by weight of the polyvinylbutyral, the epoxidized polybutadiene having a number average molecular weight of from 1,000 to 10,000 and an epoxy equivalent weight of from 200 to 2,000, and(c) from 1 to 10 parts by weight of a hardener for the epoxidized polybutadiene per 100 parts by weight of the epoxidized polybutadiene.
